Specification of Letters Patent.

Patented Oct.. 27, 1914.

Application filed September 23, 1913. Serial No. 791,300.

To all LU/0m it may concern Be it known that T, JOSEPH E. WEAVER,

a citizen of the United States, and a resident of the city of Twin Falls, in the county of Twin Falls and State of Tdaho, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

My invention relates to pumps, and has reference more particularly to balanced compound Dumps of the reciprocating type provided with translating plungers and swinging, reciprocating pump members.

An object of the invention is to provide durable, and efficient pump in which the power required to pump liquid is reduced to a minimum by balancing the moving parts of the pump.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which like characters indicate corresponding parts in all the views and in which;

Figure 1 is an elevation of an embodiment of my invention partly broken away to show the details of construction of the translating plungers; Fig. 2 is an enlarged vertical section of the enlargement in the translating plunger' and shows the detail of connection with the swinging pump members and also the stationary inlet pipe controlling the inlet to the translating plunger; Fig. 3 is a side view in the direction of the arrow on Fig. 2; Fig. 4 is a plan view in the direction of the arrow, as shown in Fig. 2; Fig. 5 is a section on line 5-5, Fig. 6; Fig. 6 is an elevated section showing the detail of construction. of the pressure equalizing mechanism; Fig. 7 is an enlarged vertical section showing the detail of construction of the swinging plunger; Fig. 8 is an enlarged vertical section of the outlet end of the translating plunger; Fig. 9 is a section on line 9-9, Fig. 6; Fig. 10 is a section on line 10-10, Fig. 9; Fig. 11 is a section on line 11-11, Fig. 3; and Fig. 12 is a section on line 12-l2, Fig. 1.

Before proceeding to a more detailed de-` scription of my invention, it must be clearly understood that in place of using a large storage tank, as shown in Fig. l, delivery `is slidably tubes can be directly associated with the outlet ends of the translating plungers.

i Referring to the drawings, 13 represents a tank from the top 'of which leads a delivery pipe 14. The tank is supported on a platform 15 which is carried by supports i6 mounted on a base 17. The bottom 18 of the tank 13 is provided with apertures 19 bordered within the tank by a member 2O provided with a recess carrying a packing member 21.l Exterior of the tank these apertures are bordered by a stufiino boX 22.

Fitting snugly through the stuzlling boX 22 and the member 2O is a hollow plunger 23 adapted to translate vertically. The upper end of the plunger 23 is provided with apertures 24 which are always above the member 20. The end portion above the apertures 24 receives a spider member 25 rigidly secured to the plunger in any suitable way and carrying arod 26 on which mounted a massive valve member 27. The rod 26 is provided with a head 28 forming a stop for 'the downward motion of the valve 27, while the central portion of the spider member 25 forms a stop for the upward motion of the valve 27.

The plunger 23 at the end lying outside of the tank 13 is provided with an enlarged portion 30 formed preferably of two intersecting cylindrical casings 31, the elements of which. are perpendicular to lines parallel to the axis of the plunger 23, the intersection of the casing being in alinement with the axis of the plunger. Rigidly secured to the enlarged portion. 30 and in alinement with the plunger 23 is a tubular member 32, which in reality forms the continuation of the plunger 23. This tubular member at the end engaging the casing 31 receives a member 33 forming valve seats for valves 34 pivotally mounted on said member and forming a check valve preventing the flow of liquid from the enlarged portion 30 to the tubular member The valves 34 are provided with projections 35 which prevent an excessive displacement of the valves 34.

The lowery end of the tubular member 32 engages a stationary tubular member 36` from where the connected to the inlet pipe water is pumped. This stationary tubular member 36 lits snugly into the tubular member 32 so that it forms a stationary inlet pipe in the same, the end of which, leading into the tubular member 32, is provided with a check valve 37, as used for admission valves in pumps.

The casings 31 are each provided on the lateral surface thereof with an opening 38, which is covered with a part-cylindrical section 39 fitting snugly over the lateral surface of the casing 31 and engaging with its edges guides 40 secured to the lateral surface of the same. rThese guides 40 prevent the part-cylindrical section from moving away from the lateral surface ofthe cylindrical casing 31 but allows the' same to swing on the lateral surface of the casings. lateral surface of each casing 31 is provided with a packing member 41 which surrounds the opening 33 and engages the part-cylin drical section 39, thereby preventing leakage through the contacting surfaces of the partcylindrical section and the cylindrical casings. l

The part-cylindrical section 39 is provided centrally on its lateral lsurface with an aperture 42 the axis of which passes through the axis of the part-cylindrical section, and which aperture receives a tubular member 43 rigidly secured thereto and formjing an integral part of the part-cylindrical section 39. rlhe axis of thistubular member necessarily passes through the axis of the cylindrical casings 31. Fitting snugly into the tubular member 43 is a tubular member 44 the non-engaged end of whichis rigidly secured to a part-cylindrical section 45 similar to the part-cylindrical section 39 and fitting on to a cylindrical casing 46. This casing is also provided with a lateral opening 47 which is covered by the part-cylindri cal section 45. rlhe part-cylindrical section 45 is guided in its motion by guides 48 similar to the guide members 40 and rigid with the lateral surface of the cylindrical casing 46. The lateral surface of the casing 46 under the part-cylindrical section 45 is provided with a packing member 49 similar to the packing member 41 and for the-same purpose.

The tubular member 44, which is necessarilyraxial with the tubular member 43, has its axis passing through the axis of the cylindrical casing 46, and, therefore, the axis of the tubular members 43 and 44 are passing through the axes of the cylindrical casing 31 and the cylindrical casing 46. The length of the lateral opening 38 in the cylindrical casing 31 and the lateral opening 47, in the cylindrical casing 46 is such that the tubular members 43 and 44 are always in communication with the interior of the casings31 and 46 respectively, no matter what the position of those members is.

The cylindrical casings 46 are rigidly secured to the supports 16 by any suitable means. Each of these casings is provided with a central partition 50 substantially parallel to the axis of translation of the The,

plunger 23 and forming a reinforcement for the casings.

The hollow plunger 23 adjacent the enlargement 30 is connected to one end of a pipe 51, which pipe extends parallel to the tubular part of the plunger' 23 and 'has its other open end within the tank 13 substantially level with the end of the hollow plunger 23. The pipe 51 is associated in its motion with the plunger 23 and is snugly fitted to the bottom of the tank 13, so as to prevent leakage. The pipe 51 adjacent its connection with the hollow plunger 23 is provided with a slide valve 52, the stem of which is engaged by the bifurcated en'd of a lever 53 pivotally mounted on the enlarged portion 30. Rigidly secured with the` lever on a pivot is a pinion 54 adapted to be engaged by teeth 55 provided on the part-cylindrical section 39. Then the pinion 54 is engaged. by the teeth -55 the slide valve is in open position establishing communication between the tank and the portion of the hollow plunger 23 below the valve 27 and above the valves 34. rlhe re son for this will appear hereinafter.

The opel ngs 19 in the bottom of the tank 13 are so p\ itioned as to be central between the cylindrical casings 46 carried by the support 16. This structure, as shown in F ig. l, not only provides balanced pumps toeach side of the central base 17 but it also provides balanced parts for each pump to each side of the enlarged portion 30. The two pumps as shown in F ig. 1 are actuated by the walking beam 56 secured to a shaft 57 mounted in the central base 17 and actuated by any suitable means. The ends of the walking beam engage a projection on the tubular member 32 whereby when the pump is actuated the two pumps are moved in opposite directions.

The action of my pump is as follows: rlhe right hand pump being at the end of its delivery stroke produced by the swinging, re-v ciprocating pump members is at the same time at the end of its suction stroke, produced by the tubular member 32 and the stationary inlet pipe 36. ln the beginning of its downward motion the pressure in the tank and the hollow plunger being the same the valve 27 will place itselfron the head 28 by the action of gravity. During the downward motion the liquid from the tubular member 32 passes through the valve 34, through the enlargements, into the tubular members 43 and 44, which increase in voluminal capacity during the downward motion of the plunger. The voluminal capacity of the'telescoping tubular members 44 and 43 on both sides of the enlargement 30 is substantially equal to the suction produced by the tubular member 32. The pressure on the right hollow plunger 23, after the vvalve 27 engages the head, 28, helps its y valves 34.

tion in which the pump at the left is shown,

the pinion 54 becomes engaged with the teeth 55 provided on the cylindrical section 39. This opens the slide valve 52 and establishes communication between the tank and hollow plunger below the valve 27 and above This equalization in pressure closes the valve 84. As the pump is moved upward by the beam the tubular member 44 enters into the tubular member 43 and reduces the volume therebetween forcing the water through the enlarged section and out through the. hollow plunger, thereby lorc-A ing the valve 27 above the apertures 24 and delivering the liquid through the said apertures until the same reaches the position shown by the pump and. the rod. It is understood that the slide valve 52 is closed at the beginning of the delivery stroke of the pumps, and the same is opened at the .end of the return stroke.
